Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522368, here are decompositions:

5 + 31522363 = 31522368
11 + 31522357 = 31522368
29 + 31522339 = 31522368
37 + 31522331 = 31522368
41 + 31522327 = 31522368
71 + 31522297 = 31522368
127 + 31522241 = 31522368
139 + 31522229 = 31522368

Showing the first eight; more decompositions exist.
